Frogspawn Macro Photo - Updated with ANOTHER New Shot

[imisky]

with the ISO at 3200 thats what is giving the photo its grainy look. i think i would try a setting a little wider than what sphelps suggested at:

ISO: 100/200 (depends if you have highlight priority set)
aperture set at: f4-5.6
shutter speed: whatever gives you a metering of slightly under the center weight.

i take all my photos at f4-8 and usually by f8 i have pictures which are sharp from corner to corner so imo theres really no need for f14-22 in our application when it comes to taking tank shots. Shooting at a wider aperture this will give you alot faster shutter speed.
